Specification of Letters Patent.

Afpplication filed July 10,

To all re/tom it may cont-c" rn:

Be it known that I, (UIIARLES E. \VOOLI", a citizen of the Unite'llStates, residing at Wynuewood, in the cfmntv of Montgomery and State ofPenusyl rania. have invented certain new and 115011 1 Improvements inShears, of which the f ollowing is a specification.

My invention relates to improvements in I cularly constructed tor use intrimming lled'ges or as pruning shea s, may be used for any purposewhere they would operate in an efficient manner.

The primary object of my invention is the provision of shears whic hwill have greatly or action with the 1 human efi ort, thus f efficiencywithout increased cutting power expenditure of very little obtaining ahigh degree 0 tiring the user.

Another object of my in rention is the pro vision of shears which can beoperated with ease and which will insu re th ttin f an increased amountof 1r t rial with a lean SlnOOtll cut without I uch strain or wear uponthe implement.

A fprther object I of my invention is the PIOYISIOII H which will beeasy to operate, WhlCll Wil be light in weight and Y durable innstruction. which may be manufacturedat, a l i d hi h 13 P point of viewwill be thoroughly oment and practical.

W'ith the above and other objects in view which will appear as thedescription proceeds, the invention consists in the novel construction,combination and arrangement of parts, hereinafter described and claimed,it being understood that changes in the precise embodiment of theinvention herein disclosed can be made without departing from the spiritof the invention.

In the accompanying drawing, I have illustrated one complete example ofthe physical embodiment of my invention constructed according to thebest mode I have so far devised for the practical application of theprinciples of my invention.

Figure 1 represents a top plan view of my shears with the parts inclosed position. Fig. 2 represents a similar view with the shears openfor cutting, and Fig. 3 represents a sectional view taken on the line3-3 of Fig. 2.

My shears are of extremely simple c011- 65 struction and may be said toconsist of the pair of handles 1, having their outer free Patented Dec.26, 1916. 1916. Serial No. 108,410.

ends formed with finger loops 2, and their inner ends 3 engaging andpivoted to the inner ends 4 of the pair of cutting blades 5, by means ofthe pin or stud 6; and the pair of crossed oppositely curved levers orfulcrums 7 having their ends 8 pivoted at 9 to the finger loops 2 andtheir other ends 10 f rked and pivoted by the pins 11 at or near .10outer free ends of the blades 5, said levers 7 being pivoted by means ofthe pin or stud 12 at their point of intersection and formed with theguiding shoulder or abutment 13 for the handles 5.

From the foregoing description taken in connection with the drawings themanner of using my shears will be readily understood, and it will beapparent that the opening of the handles also opens the cutting blades,and that the closing of the handles causes the blades to cut thematerial or object with a clean, smooth shear cut, this beingaccomplished with ease and rapidity.

It will also be apparent that by my construction I secure a very strongand powerful cutting action with the expenditure of very little force oreffort and that in this manner the shears are capable of cutting thicksubstance or material in a rapid and efficient manner with little effortand without tiring the user which is a great advantage.

Tt will also be understood that my shears, while possessing theadvantages stated, are very simple, durable and inexpensive, willwithstand very hard usage and may be employed for many purposes, andgenerally are desirable and practical.

I claim 1. The shears herein described, consisting of the handles havingfinger loops formed on their outer free ends, the pair of cutting bladeshaving their inner ends pivoted to the inner ends of said handles, and apair of oppositely curved levers connected to said blades at or neartheir outer free ends and to said handles near their outer free ends.

2. The shears herein described, consisting of the handles having fingerloops, the pair of cutting blades having their inner ends pivoted to theinner ends of said handles, and a pair of crossed oppositely curvedlevers having one and connected at or near the outer free end of saidblades and the other connected to said handles at or near their outerfree ends.

3. The shears herein (lesrrihmh consisting of the hzunlles havingfingerloops, the pair of cutting hludes having their inner ends pivoted to theinner ends of said handles,

5 and :1 pair of crossed oppositely curved le vers having their endspivoted to the blades near their outer free ernls and to the handlesnear their outer free ell ls, said crossed 0pp0- sitely enrvecl leversheing pivoted at their 10 point of intersection.

1. The combination with :1 pair of cutting blades and handles having acommon pivot renter, of 11 pair: of erossed levers each pivoted at oneend to a; cutting blade and at the other end to 91 handle. 15 Intestimony w hereof I afiix my signature in the presence oit twoWitnesses.
